VANGUARD DEB, 61446
Orbit data source: Space-Track
VANGUARD DEB, 61446 is space debris in LEO originally from a launch on Tue, 17 Feb 1959 UTC launched from the Air Force Eastern Test Range (AFETR). Debris objects in space refer to the collection of defunct objects orbiting the Earth. Examples of debris include non-operational satellites, rocket bodies, and fragments generated from explosions, collisions, or faulty payload assembly.
